Why not just multiply the pet's age by 7?

The '7-year rule' is biologically inaccurate. Pets undergo rapid development in their early years and a different maturation process as they age. Our tools, such as `convert_dog_age`, use scientifically backed non-linear curves to provide much more precise estimates.

How does dog size affect the calculation?

Canine aging is heavily influenced by breed mass. Small dogs, medium dogs, and large dogs follow distinct biological trajectories. The `convert_dog_age` tool requires a size category to apply the correct growth model.

Can I determine if my pet is a senior?

Yes. After calculating the human-equivalent age, you can use the `get_pet_life_stage` tool to determine if your pet is in the Infant, Adult, Senior, or Geriatric stage.

The Pet Age Converter is a precision biological aging engine that moves beyond the simplistic 'one year equals seven years' myth. By utilizing non-linear, species-specific growth curves, this MCP server provides accurate human-age equivalents for pets. For dogs, the tool accounts for size-dependent aging trajectories, applying different models for small, medium, and large breeds. For cats, it implements a unified feline maturation curve. Use convert_dog_age to find the human age of a dog based on its breed size, convert_cat_age for cats, and get_pet_life_stage to identify biological milestones like Puppy, Adult, or Senior.
